odd one this, or maybe not.
Daniel defense A3 upper, here's the problem.

1. With no mag in and holding the rifle pointing straight down, bolt jams (cannot charge) If rifle is straight and level or on it's side or upside down then no problem.
2. Bolt jams with an empty mag inserted, however if i put a round in the chamber and close the bolt then insert an empty mag it will open and extract the round and hold open on the empty mag with no problems. If I then close the bolt on the empty mag.....lock up again.

Am I missing something fundamental, I've tried 5 different mags all with the same result.

cheers for any ideas.

Brit AR's don't have operating gas systems, correct?  Are there any other modifications done?

How far from being fully into battery does it jam?  If you pick up your AR and shake it hard do you hear a rattle on the inside?  Have you checked to see that your bolt slides freely in your carrier?
